Abstract：An output feedback controller based on the robust integral of the sgn of the error(RISE)method is proposed for the three-phase inverter with matched and unmatched disturbances,where the needs of performance optimization and cost reduction are taken into account.Firstly,the matched and unmatched disturbances are converted into equivalent lumped disturbances by es-tablishing the system error dynamic model,on this basis,the controller is designed.Secondly,a robust state observer with anti-dis-turbance performance is constructed to estimate the measured state signal.Thirdly,a feedforward compensation term is integrated to improve the voltage tracking precision and an integral robust term is employed to handle lumped disturbances.Finally,the asymptot-ic convergence of observational error and tracking error are derived according to Lyapunov stability analysis,furtherly,the feasibili-ty and effectiveness of the proposed strategy are demonstrated by simulation results.
